Later, under the untypical parasternal four-chamber view which can thoroughly display the ostium of coronary sinus, the catheter was promoted further to the ostium of coronary venous sinus. Then the echocardiography technician adjusted the transducer of TTE in order to thoroughly confirm the position of the catheter tip. After confirming the position of catheter tip in the coronary venous sinus, the operator inserted the catheter into the coronary venous sinus for 3～4 mm farther. It was noted that if resistance was encountered by operator, the operation must be stopped, which was the same as x-ray fluroscopy as image guiding. TTE guiding His bundle elactric cahteter、high right atrium electric cahteter and right ventricular electric catheter in site: It is difficult using TTE singly since there are too many crossroads in inferior venous.

本研究结果显示，(1)单独应用TTE作为影像学引导进行冠状窦电极导管置放的成功率为93.8％～96.7％，并且应用TTE作为影像学引导放置专用冠状窦电极导管和普通电极导管的成功率和放置时间在统计学上无显著差异；(2)TTE作为影像学引导，除过度肥胖患者外，可完全替代X线引导进行冠状窦电极导管置放，包括鞘管和扩张管的放置、指引导丝在静脉而非动脉内的证实均可由TTE完成引导，且较X线C型臂有一定优越性；(3)TTE结合普通X线胃肠透视机作为影像学导引，可顺利完成心内电生理检查时导管的安全到位，而不需昂贵的X线C型臂，可将心内电生理检查扩大到广大的基层医院；(4)TTE较X线更易和更早期发现介入治疗的并发症如急性心包填塞等，对并发症的防治甚至挽救病人的生命至为重要；(5)动物实验研究表明，TEE可引导射频导管消融术时大头电极导管成功到位。

This paper gives a design to measure the vibration with photogrammetric survey,and at the same time,the method of bundle adjustment is applied to modify the position of targets.

因此设计了非接触的摄影测量方案，并提出了采用光束平差法来修正目标点位置坐标，并且在某些相机参数可能发生变化的情况下，采用光束平差的方法来修正相机的外参数，大大提高了本方案的鲁棒性能。
